Stackable armchair

Claim 2

A stacking armchair including in combination: a front frame having two bottom rail portions, two front leg portions, two seat side rail portions, a rear connecting member connecting together the rear ends of the side rail portions and extending therebeyond to the outboard ends, and a front brace portion bridging between the front leg portions, said front frame being made from thin rod stock, the rear of each bottom rail portion having a turned-up generally vertical terminal portion, two rear leg members of rod stock that is larger in diameter and greater in strength and stiffness than the rod stock from which the front frame is made, said rear leg member having a lower end welded to the said terminal portion, said rear leg portion being welded also to said outboard ends of the rear connecting member and having an upper portion extending thereabove, a seat secured to and supported by said front frame, a back secured to and bridging across the upper portion of said rear leg members, said upper portions of said rear leg members each being shaped to provide a short outwardly extending generally horizontal portion, a forwardly extending arm-support portion parallel to the seat-supporting side rail portion but outboard from it, and a chair arm supported by said arm-support portion.

Claim 3

The stacking armchair of claim 1, wherein each said bottom rail portion has a front glide and a rear glide extending below said bottom rail portion and a pair of spacer members extending above said bottom rail portion and aligned relatively to said glides to engage the glide of a like chair to be stacked thereon.

Claim 4

The stacking armchair of claim 1 wherein said arm comprises a flat arm-support plate welded to said arm-support portion in a horizontal position and an arm rest secured to said plate.

Claim 5

The stacking armchair of claim 3 wherein said arm rest extends about halfway between said back and said front legs.

Claim 6

A stacking armchair including in combination: a front frame member having two bottom rail portions, two front leg portions, two seat side rail portions, a rear connecting portion connecting together the rear ends of the side rail portions and having short portions extending therebeyond to outboard ends, and a front brace portion bridging between the front leg portions, all made from thin rod stock, the rear of each bottom rail portion having a turned-up generally vertical terminal portion, two rear leg members of rod stock having greater thickness, strength, and stiffness than the rod stock from which the front frame member is made, each said rear leg member having a lower end butt-welded to the top of a said terminal portion, each said rear leg portion being welded also to a said outboard end of said rear connecting portion and upper portions extending thereabove to an upper end, a seat secured to and supported by said side rail portions and said rear connecting member, a back secured to said upper portions of said rear leg members, each said rear leg member having a horizontal portion extend outwardly of said chair at its upper end, said horizontal portion then being bent forwardly of said chair to provide an arm-support portion parallel to the seat-supporting side rail portion but outboard from it, said arm-support portion extending forward about halfway from the rear of the chair to its front, a flat arm-support plate secured to said arm-support portion of the frame and an armrest secured to said arm-support plate.

Claim 7

A stacking armchair including in combination: a front frame member having two bottom rail portions, two front leg portions, two seat side rail portions, a rear connecting portion connecting together the rear ends of the side rail portions and having short portions extending therebeyond to outboard ends, and a front brace portion bridging between the front leg portions, all made from thin rod stock, the rear of each bottom rail portion having a turned-up generally vertical terminal portion, two rear leg members of rod stock having greater thickness, strength, and stiffness than the rod stock from which the front frame member is made, each said rear leg member having a lower end butt-welded to the top of a said terminal portion, each said rear leg portion being welded also to a said outboard end of said rear connecting portion and upper portions extending thereabove to an upper end, a seat secured to and supported by said side rail portions and said rear connecting member, a back secured to said upper portions of said rear leg members, each said rear leg member having a horizontal portion extend outwardly of said chair at its upper end, said horizontal portion then being bent forwardly of said chair to provide an arm-support portion parallel to the seat-supporting side rail portion but outboard from it, said arm-support portion extending forward about halfway from the rear of the chair to its front, a flat arm-support plate secured to said arm-support portion of the frame and an armrest secured to said arm-support plate.

Claim 8

The stacking armchair of claim 1 having two pairs of glides secured to and extending below each said bottom rail, one below the front end thereof and one below the rear end, two pairs of spacer members attached to and extending upwardly from each said bottom rail, one at the front and one at the rear, said spacer members being aligned with their associated glides so as to engage approximately centrally with the corresponding glides of a like chair stacked thereabove.

Claim 9

The stacking armchair of claim 5 wherein each said plate is welded to its said arm-support portion and is secured to said armrest by screws extending up from the bottom of said plate through openings into blind threaded openings in said armrest.

Claim 10

A stacking armchair including in combination: two symmetrical front frame members, each having a bottom rail portion, a front leg portion, and a seat side rail portion, the rear of each bottom rail portion having a turned-up generally vertical terminal portion, said front frame members being made from thin rod stock, a rear connecting member connecting together the rear ends of the side rail portions and having short portions extending therebeyond to the outboard end, a pair of rear leg members of rod stock being thicker and having greater strength and stiffness than the rod stock from which the front frame members are made, each said rear leg member having a lower end welded to said terminal portions, said rear leg portions being welded also to said outboard ends of said rear connecting member, and having an upper portion thereabove, a seat secured to and bridging between said side rail portions and secured to said rear connecting member, a back secured to and bridging across the upper portions of said rear leg portions, each said rear leg member having a short outwardly extending horizontal portion that is bent to provide a forwardly extending arm-support portion parallel to the seat-supporting side rail portion but outboard from it, and a chair arm secured to each said arm-support portion.

Claim 11

A stacking armchair including in combination: two symmetrical front frame members, each having a bottom rail portion, a front leg portion, and a seat side rail portion, the rear of each bottom rail portion having a turned-up generally vertical terminal portion, said front frame members being made from thin rod stock, a rear connecting member connecting together the rear ends of the side rail portions and having short portions extending therebeyond to the outboard end, a pair of rear leg members of rod stock being thicker and having greater strength and stiffness than the rod stock from which the front frame members are made, each said rear leg member having a lower end welded to said terminal portions, said rear leg portions being welded also to said outboard ends of said rear connecting member, and having an upper portion thereabove, a seat secured to and bridging between said side rail portions and secured to said rear connecting member, a back secured to and bridging across the upper portions of said rear leg portions, each said rear leg member having a short outwardly extending horizontal portion that is bent to provide a forwardly extending arm-support portion parallel to the seat-supporting side rail portion but outboard from it, and a chair arm secured to each said arm-support portion.
